So recently, I've been looking at a lot of Banksy's work and it kind of got me in a environmentalist mood. And when I get into such a mood, I create depressing art like this. But I do hope it helps you talk about the importance of renewable energy and environmental friendliness.

Say no to palm oil!

Say no to palm oil and avoid buying products that includes palm oil, and wear this shirt to show that you will not stand for this unnecessary killing of our planet.
